This page contains pictures and information about Braconid Wasps in subfamily Opiinae that we found in the Brisbane area, Queensland, Australia.
 
Wasps in this Subfamily Opiinae are small in size. They are often orange or yellow in colours. Most of them parasitic on larvae of fruit flies.

? Opius sp., body length 4mm 
We found this Braconid Wasp on the fruits of Wild Tobacco (Solanum mauritianum). Those Wild Tobacco plants are common weeds along creeks in Brisbane. Most of the Wild Tobacco fruits were infected by a kind of small fruit flies. There were the wound on the fruits, if we open it we will see the small fruit fly larvae. Sometimes we saw this small wasp,  examining the infected fruits. The wasp will insert her ovipositor into the wound. We believed she laid eggs which the larvae will hatch and  parasite on the fruit fly larvae. Please also check this web page.

We have a plum plant in our backyard. Some fruits were infected by a kind of small fruit flies Tephritidae. There were the wound on the fruits, if we open it we will see the small fruit fly larvae. Sometimes we saw the small wasp, as the about pictures, examining the infected fruits. After checking the wound on the fruit, the wasp will insert her ovipositor into the wound. We believed she laid eggs which the larvae will hatch and  parasite on the fruit fly larvae.
